Breath alcohol elimination rate as a function of age, gender, and drinking practice.

The objective of this study was to determine whether breath alcohol elimination rate varies as a function of age, gender, and drinking practice, factorially combined. Eighty-four men and 84 women drank enough alcohol to produce peak BrACs of .110 g/210 L for heavy and moderate drinkers and BrACs of .

The Long Beach/Fort Lauderdale relative risk study.

Problem: The role of alcohol as a major factor in traffic crash causation has been firmly established. However, controversy remains as to the precise shape of the relative risk function and the BAC at which crash risk begins to increase.

Methods: This study used a case-control design in two locations: Long Beach, California, and Fort Lauderdale, Florida.

Improving patient flow at an outpatient clinic: study of sources of variability and improvement factors.

This paper focuses on analyzing and improving patient flow at an outpatient clinic of the Indiana University Medical Group. A structured process analysis and improvement approach was used to identify sources of variability and improvement factors. A process map, that matched the flow process at the clinic, was developed and validated.

Developing limits for driving under cannabis.

Objective: Development of a rational and enforceable basis for controlling the impact of cannabis use on traffic safety.

Methods: An international working group of experts on issues related to drug use and traffic safety evaluated evidence from experimental and epidemiological research and discussed potential approaches to developing per se limits for cannabis.

Results: In analogy to alcohol, finite (non-zero) per se limits for delta-9-tetrahydrocannabinol (THC) in blood appear to be the most effective approach to separating drivers who are impaired by cannabis use from those who are no longer under the influence.
